title: Prolidase deficiency with iminodipeptiduria: biochemical investigations and first results of attempted therapy.
abstract: A 33-year-old female patient with chronic recurrent leg ulcerations was shown to present a massive iminodipeptiduria which seemed to be attributable to disturbance of collagen metabolism. Biochemical investigations confirmed an hereditary prolidase deficiency. A treatment was tried for the first time and showed a good biochemical result and a clinical improvement.
